ScienTific Reasons for more visit www.lahoremark.com
Why a white roof Keep a house cooler as compared to black roof?
This is due to the process of reflection of heat rays. White colour has capacity to ret heat rays & absorbs less heat as compared to black colour.
That is why while roof keep a house cooler as compared to black roof.
Explain why we perspire before rain?
The occurs due to greater quantity of moisture in air, before raining there is a large amount of moister in air which causes us to perspire before rain.
Why fanning produces cooling effect in body?
This is due to the process of evaporation, which has cooling effect. When a fan is starts the moving air increases evaporation, which produces cooling effect in body.
Explain why a thick glass tumbles cracks when very hot water is poured into it?
This occurs due to the process of expansion. When hot water is poured into a glass troubler or jug it causes expansion of inner surface & uneven expansion breaks enter layer.
The earth bulges out at the equator, why?
This is due to the shape of the earth. The earth is not a true sphere but it is an ellipron. The equatorial diameter of the earth is 12756.2711 km. While it’s polar diameter is 12713.5 km. The difference between its equatorial & polar diameter is about 43 kilometers the rotation the earth on its axis produces as centrifugal force which increases its equatorial diameter.
Due to this reason the earth bulges at the equators.
Why the sun appears red at the time of sunset & sunrise?
This occurs due to scattering of light by small particles of dust & smoke near the surface of the earth. At the time of sunset and sunrise light rays have to cover a travel of greater distance. Soduring their travel dust & smoke scatters all others colors of light except red & red light rays travel unhindered & reach to use, that is why sun appears red.
Why meat takes long time to cook on the mountains?
This occurs due to air pressure. The relation between air pressure and boiling point is directly proportional when air pressure increase, boiling point also increases on other hand when thepressure, decreases, boiling point of substance decreases.
As the mountains are concerned, the air pressure at the mountains is low due to height. That is why takes long time to cook at mountains.
Why milk is considered as an ideal food?
Milk is considered as an ideal food due to following reasons
•
It contains all constitute of balanced diet.
•
Milk contains fat.
•
Milk has high nutritional value because it contains proteins as well as minerals.
Why the colour of sky is blue?
The colour of the sky is blue due to following reason.
•
There are minute dust particles and water vapour in the atmosphere which scatter blue colour at higher altitudes.
What is galaxy ? For more detail please visit www.lahoremark.com
Galaxy:
A galaxy is a system of many thousands of million of stars together with interstellar gas and dust.
OR
Galaxy is a fundamental unit of universe.it is composed of hundreds of thousands stars together with intercellular gas & dust.
Origin of Galaxies:
The galaxies resulted from the accumulation of gas on the proto-galaxies that were formed by density fluctuations and gravityinstabilities in the expanding primordial fireball. It is thought that they originally consisted only of those formed in the big bang (mainly hydrogen and Helium).
Number of Galaxies:
The number of galaxies in the universe is estimated to be between 100 billion and a trillion (1011 to 1012). Each galaxy contains about 100 billion stars.
Classification:
The galaxies were classified by Hubble in 1924. According to his thesis, there are three types of galaxies, which are as under.
01)
Elliptical galaxies.
02)
Spiral galaxies.
03)
Irregular galaxies.
Elliptical Galaxies:
Elliptical galaxies (E) appear as luminous elliptical disc with a smooth distribution of light. Their surface brightness decreases out ward from the center. Elliptical galaxies are further divided into EO-7, according their aspect in the sky. For example, EO types are seen face on as circular discs, while E-7 types are seenalmost edge on.
Spiral Galaxies:
Spiral galaxies are either normal(S), in which spiral-shared arms emerge directly form the center. Spiral galaxies are further divided into types a, b and c, depending on the extant of theunwinding of the arms and on the relative clarity of the arms and the nucleus (Centre).
Irregular Galaxies:
Irregular galaxies do not have a definite structure. However, two types are distinguished i.e. Irr I and Irr II.

Scientific Reason
Why does water always seem shallower than it is?
Water always seems shallower due to refraction of light. The light rays which come from the bottom of the pool travel air. During their travel the ray bent when pass from denser water to rear (air) medium. When the of the coil at a point which above the position. There fore the coil seems to be slightly raised & ultimately pool appears shallower than it really is.
What is the function of making a wire earth?
This is done in order to save our selves from loss in the event of short circuiting. If the electric appliance is properly e earthed, it causes current to pass to the earth easily without any harm to the users. If the appliance is not properly earthed, it will cause a server shock to the user.
How many colors seen in rainbow?
A rainbow is composed of following seven colours.
(1) Violet (5) Indigo
(2) Blue (6) Green
(3) Orange (7) Yellow
(4) Red
Why do we use woolen cloths for protecting over selves from cold?
Basically the wooden clothes are coarse clothes woolen clothes have capacity to retain temperature or heart inside them & do not allow it to escape out. At the same it does not allow to enter the cold inside.
That is why we use woolen clothes for protecting our selves form cold.
Why is rose red and grass green in day light?
This is all due to tendency of rose & grass to absorb constituent of light. Rose appears in the day light because it absorbs all others colours of light except red. In this way, grass absorbs all other constituent of while light except green that is why it appears green.
Ho can bats fly in dark?
How can bats fly in the dark avoiding obstacles?

Why do we bring out hand close to mount while shouting to somebody at a distance?
We always bring out hands close to mount while shouting because by bringing the hands close to the mouth, the sound energy is not allowed to spread in different directions and we make it unidirectional. By doing this we are able to produce loud sound.
Why copper rods and preferred to iron rods making lighting conductors?
Copper rods are preferred to iron rods for making lighting conductors for the following reasons.

Black sea , what is black sea ?
Black sea
Black sea is the sea between Europe and Asia, connected with the Mediterranean by narrow waterways. Area 460000 sq. km .It has been especially important to Russia, which has few warm-water seaports, and to Turkey, which controlled the rest of its shores 19th century.
